Does australia use pal or ntsc video format?
im making a dvd home movie to sent to my uncle in australia for christmas but i need to know what format to use, does australia use the european pal format, the american ntsc format, or does it use a different format?

PAL see here http://www.videouniversity.com/standard..
The basics of PAL and the NTSC system are very similar; a quadrature amplitude modulated subcarrier (typically at approximately 4.43 MHz for PAL, and 3.58 MHz for NTSC) carrying the chrominance information is added to the luminance video signal to form a composite video baseband signal (CVBS). The SECAM system, on the other hand, uses a frequency modulation scheme on its colour subcarrier. The name "Phase Alternating Line" describes the way that the phase of part of the colour information on the video signal is reversed with each line, which automatically corrects phase errors in the transmission of the signal by cancelling them out. (Lines where the colour phase is reversed compared to NTSC are often called PAL or phase-alternation lines, which justifies one of the expansions of the acronym, while the other lines are called NTSC lines.) Early PAL receivers relied on the imperfections of the human eye to do that canceling, however this resulted in a comb-like effect on stronger phase errors. Thus, most receivers use a delay line which stores the received colour information on each line of display; an average of the colour information of the current line and that of the previous line is then used to drive the picture tube. This reduces vertical colour resolution compared to the NTSC system, however since the human retina also has a colour resolution that is much lower than its brightness resolution, this effect is not visible. NTSC, PAL, and SECAM all have chrominance bandwidth (horizontal colour detail) reduced greatly compared to the luminance signal anyway.
Countries and territories that use PAL B, G, D or K:
Oceania
* Australia (uses PAL-B (UHF band), but Zweiton for stereo)
* Christmas Island (see Australia)
* Cook Islands (see New Zealand)
* Easter Island
* Fiji will probably convert to DVB-T by 2010
* New Zealand (uses NICAM for stereo)
* Norfolk Island (see Australia)
* Papua New Guinea
* Solomon Islands
* Tonga, Tonga is converting to NTSC and probably ATSC
* Vanuatu
Note about Australia & NZ with respect to stereo audio:
* Australia & NZ have identically allocated UHF TV bands.
* NZ's use of NICAM means that imported Australian TV sets only work in mono.
* NZ and Australia have incompatible VHF TV bands, namly the primary carrier frequencies are different. In some cases the offsets are minor, but in others very significant.
* DVB-T (using UHF band) may eleminate the incompatibility issues between Australia and NZ's TV frequency allocations.
